Well, half question if I got this right, talent wise:
Tiera is the fastest when it comes to learning things due to her memory, but has anger issues. On the other hand she is also a natural leader with a knack for finding ways to get things done smoothly without being forced to resort to underhanded manipulation.
Timon is the best at analytical thinking, the smartest char so far, but is somewhat insane
Both can build on Tor's ideas, apply them in different ways and improve or combine them but they're not really inventive. Almost everything they've done so far except the changing stones into other things idea was based on someting Tor did before, though the application can be vastly different of course.
Tor is an extremely focused workaholic who always reads all the fields of everything and a master of direct effect magic thanks to that focused control over his own mind as well as a very inventive person...with some rather outlandish ideas occasionally (flying rivers, giant purple dragons, direct feedback from the mind to devices and oh, let's not even mention the idea of turning a shield meant for combat to make magic houses...I mean it works, but you have to be very unusual to have so many strange ideas in such a short period of time. Timon or Tiera never would have thought of those, they're inherently too practical in their thought process). His faults are that he doesnt understand the first thing about limits (which is both good and bad) or people. He seems especially blind to a lot of emotions that he really can't seem to relate to.
Terry seems not quite as smart as Tor or Tiera, very noble and decisive plus he is apparently good at fitting in with almost any kind of crowd, be it ancients or family or a city full of orphans, not to mention every nationality around. Again, a decent wizard and amazing warrior, probably the best of the young ancients, who appears to see both magic and physical power as tools to achieve the noble goals he sets himself. From what I've read I assume that he probably won't stop trying to reach a goal no matter what happens or who tries to stop him.
Terlee seems as smart as Tor and Tiera and every time she appears I get the impression of a beatiful white silk glove with an iron fist hidden beneath, or a snake that doesn't move until just the right moment and then moves so fast nobody sees it coming. Calculating and cautious. Not evil or anything, but...just a bit scary somehow? She also seems to be the most 'noble' as in aristocratic of the bakers.
Taman on the other hand seems very smart and very conscious of basic needs, a person who sees simpler things more clearly where most of her siblings are preoccupied with the big picture. I got that impression because of the devices she makes. They're all very practical in the every day life of the more common citizen, much more so than the powerful and flashy stuff with mind controlled devices, superweapons and fancy techniques Tor, Tiera and Timon throw around. I think that would be a really great thing to get Soam back on track, to start with magic supported farming and transportation and other practical things. Who knows, maybe Soam could become vital in terraforming other planets and such later on?
Then Todd and the oldest baker son...they both seem...well...simpler, not quite as smart in Todd's case though I think the oldest is intelligent, peaceful and calm. He might become someone who could at least try to rein siblings like Terry, Tiera or Tor in when they get too far away from the normal people's lives. Probably not Timon. Not leadership material or people who would confront the powerful, but both of them might help ground the rest of the family maybe?
I have no idea about the others.
Did I get the right impression about those chars or am I way off?
